You'll learn how to define class intervals and calculate their size, identify the lower and upper limits of each class, and distinguish between inclusive and exclusive class formats—especially useful when handling discrete versus continuous data. We also explain how to find the class mark (or midpoint), which plays a key role in further statistical analysis like calculating the mean. Using clear visuals and real-world examples, this tutorial makes organizing raw data intuitive and accessible for learners at any level. Courses on Khan Academy are always 100% free.

In this video, we’ll go step by step through cumulative frequency, the “less than” and “more than” methods, and how to plot both types of ogives clearly. With easy visuals and simple explanations, you’ll see not just how to draw them, but also why they work. By the end, you’ll be confident in interpreting data through ogives and ready to apply the concept in real-world problems and exams. Courses on Khan Academy are always 100% free.
